Guide to the Secure Configuration of Red Hat Enterprise Linux 7
with profile C2S for Red Hat Enterprise Linux 7This profile demonstrates compliance against the U.S. Government Commercial Cloud Services (C2S) baseline. This baseline was inspired by the Center for Internet Security (CIS) Red Hat Enterprise Linux 7 Benchmark, v2.1.1 - 01-31-2017. For the SCAP Security Guide project to remain in compliance with CIS' terms and conditions, specifically Restrictions(8), note there is no representation or claim that the C2S profile will ensure a system is in compliance or consistency with the CIS baseline.

This guide presents a catalog of security-relevant
configuration settings for Red Hat Enterprise Linux 7. It is a rendering of
content structured in the eXtensible Configuration Checklist Description Format (XCCDF)
in order to support security automation. The SCAP content is

Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The DISA STIG, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.

| Description | SSH allows administrators to set an idle timeout
interval.
After this interval has passed, the idle user will be
automatically logged out.
ClientAliveInterval 300The timeout interval is given in seconds. To have a timeout of e.g. 10 minutes, set interval to 600. If a shorter timeout has already been set for the login shell, that value will preempt any SSH setting made here. Keep in mind that some processes may stop SSH from correctly detecting that the user is idle. | ||||||||
| Rationale | Terminating an idle ssh session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been let unattended. | ||||||||

| Warnings | warning
The system needs to be rebooted for these changes to take effect. warning
The Federal Information Systems Modernization Act (FISMA), requires cryptography protecting sensitive
or valuable data to undergo FIPS 140 validation. The U.S. National Institute of Standards and
Technology (NIST) views unvalidated cryptography as providing no protection to the information or
data—in effect the data would be considered unprotected plaintext. If the agency specifies that the
information or data be cryptographically protected, FIPS 140 is applicable. This configuration
check will fail on platforms lacking FIPS 140 validation, such as the CentOS, Scientific Linux,
and Fedora projects, even if FIPS-approved ciphers can be installed and enabled.
See https://csrc.nist.gov/Projects/cryptographic-module-validation-program for more information about the Cryptographic Validation Program. A list of FIPS validated cryptographic modules can be found at http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/1401vend.htm. The validated cryptographic modules only apply to the products and companies listed in the active validation list. | ||||||

| Description | Limit the ciphers to those algorithms which are FIPS-approved.
Counter (CTR) mode is also preferred over cipher-block chaining (CBC) mode.
The following line in Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbcThe man page sshd_config(5) contains a list of supported ciphers.
The following ciphers are FIPS 140-2 certified on Red Hat Enterprise Linux 7: - aes128-ctr - aes192-ctr - aes256-ctr - aes128-cbc - aes192-cbc - aes256-cbc - 3des-cbc - rijndael-cbc@lysator.liu.se Any combination of the above ciphers will pass this check. Official FIPS 140-2 paperwork for Red Hat Enterprise Linux 7 can be found at http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp2630.pdf | ||||||||
| Rationale | Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore
cannot be relied upon to provide confidentiality or integrity, and system data may be compromised.
| ||||||||
| Warnings | warning
The system needs to be rebooted for these changes to take effect. warning
The Federal Information Systems Modernization Act (FISMA), requires cryptography protecting sensitive
or valuable data to undergo FIPS 140 validation. The U.S. National Institute of Standards and
Technology (NIST) views unvalidated cryptography as providing no protection to the information or
data—in effect the data would be considered unprotected plaintext. If the agency specifies that the
information or data be cryptographically protected, FIPS 140 is applicable. This configuration
check will fail on platforms lacking FIPS 140 validation, such as the CentOS, Scientific Linux,
and Fedora projects, even if FIPS-approved ciphers can be installed and enabled.
See https://csrc.nist.gov/Projects/cryptographic-module-validation-program for more information about the Cryptographic Validation Program. A list of FIPS validated cryptographic modules can be found at http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/1401vend.htm. The validated cryptographic modules only apply to the products and companies listed in the active validation list. | ||||||||

| Description | By default, DConf uses a binary database as a data backend. The system-level database is compiled from keyfiles in the /etc/dconf/db/ directory by the dconf updatecommand. |
| Rationale | Unlike text-based keyfiles, the binary database is impossible to check by OVAL. Therefore, in order to evaluate dconf configuration, both have to be true at the same time - configuration files have to be compliant, and the database needs to be more recent than those keyfiles, which gives confidence that it reflects them. |

| Description | If the system is joined to the Red Hat Network, a Red Hat Satellite Server, or a yum server, run the following command to install updates: $ sudo yum updateIf the system is not configured to use one of these sources, updates (in the form of RPM packages) can be manually downloaded from the Red Hat Network and installed using rpm.
NOTE: U.S. Defense systems are required to be patched within 30 days or sooner as local policy dictates. |
| Rationale | Installing software updates is a fundamental mitigation against the exploitation of publicly-known vulnerabilities. If the most recent security patches and updates are not installed, unauthorized users may take advantage of weaknesses in the unpatched software. The lack of prompt attention to patching could result in a system compromise. |

| Description | To ensure the system can cryptographically verify base software packages come from Red Hat (and to connect to the Red Hat Network to receive them), the Red Hat GPG key must properly be installed. To install the Red Hat GPG key, run: $ sudo subscription-manager registerIf the system is not connected to the Internet or an RHN Satellite, then install the Red Hat GPG key from trusted media such as the Red Hat installation CD-ROM or DVD. Assuming the disc is mounted in /media/cdrom, use the following command as the root user to import
it into the keyring:
$ sudo rpm --import /media/cdrom/RPM-GPG-KEYAlternatively, the key may be pre-loaded during the RHEL installation. In such cases, the key can be installed by running the following command: sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Rationale | Changes to software components can have significant effects on the overall security of the operating system. This requirement ensures the software has not been tampered with and that it has been provided by a trusted vendor. The Red Hat GPG key is necessary to cryptographically verify packages are from Red Hat. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

open *.* @loghost.example.com To use TCP for log message delivery: *.* @@loghost.example.com To use RELP for log message delivery: *.* :omrelp:loghost.example.com There must be a resolvable DNS CNAME or Alias record set to "logcollector" for logs to be sent correctly to the centralized logging utility. | ||||||||||||||
| Rationale | A log server (loghost) receives syslog messages from one or more systems. This data can be used as an additional log source in the event a system is compromised and its local logs are suspect. Forwarding log messages to a remote loghost also provides system administrators with a centralized place to view the status of multiple hosts within the enterprise. | ||||||||||||||

| Rationale | ICMP redirect messages are used by routers to inform hosts that a more
direct route exists for a particular destination. These messages modify the
host's route table and are unauthenticated. An illicit ICMP redirect
message could result in a man-in-the-middle attack.

| Description | To set the runtime status of the $ sudo sysctl -w net.ipv4.conf.all.accept_source_route=0If this is not the system default value, add the following line to a file in the directory /etc/sysctl.d: net.ipv4.conf.all.accept_source_route = 0 |
| Rationale | Source-routed packets allow the source of the packet to suggest routers
forward the packet along a different path than configured on the router,
which can be used to bypass network security measures. This requirement
applies only to the forwarding of source-routerd traffic, such as when IPv4
forwarding is enabled and the system is functioning as a router.

| Description | The grub2 boot loader should have a superuser account and password
protection enabled to protect boot-time settings.
$ grub2-setpasswordWhen prompted, enter the password that was selected. NOTE: It is recommended not to use common administrator account names like root, admin, or administrator for the grub2 superuser account. Change the superuser to a different username (The default is 'root'). $ sed -i s/root/bootuser/g /etc/grub.d/01_users To meet FISMA Moderate, the bootloader superuser account and password MUST differ from the root account and password. Once the superuser account and password have been added, update the grub.cfg file by running:
grub2-mkconfig -o /boot/grub2/grub.cfgNOTE: Do NOT manually add the superuser account and password to the grub.cfg file as the grub2-mkconfig command overwrites this file. | ||||||||||||||||||||||||||||||
| Rationale | Password protection on the boot loader configuration ensures users with physical access cannot trivially alter important bootloader settings. These include which kernel to use, and whether to enter single-user mode. For more information on how to configure the grub2 superuser account and password, please refer to | ||||||||||||||||||||||||||||||

| Description | To specify the number of days after a password expires (which
signifies inactivity) until an account is permanently disabled, add or correct
the following lines in INACTIVE=30A value of 35 is recommended; however, this profile expects that the value is set to 30.
If a password is currently on the
verge of expiration, then 35 days remain until the account is automatically
disabled. However, if the password will not expire for another 60 days, then 95
days could elapse until the account would be automatically disabled. See the
useradd man page for more information. Determining the inactivity
timeout must be done with careful consideration of the length of a "normal"
period of inactivity for users in the particular environment. Setting
the timeout too low incurs support costs and also has the potential to impact
availability of the system to legitimate users. | ||||||||
| Rationale | Disabling inactive accounts ensures that accounts which may not have been responsibly removed are not available to attackers who may have compromised their credentials. | ||||||||

| Description | If any account other than root has a UID of 0, this misconfiguration should
be investigated and the accounts other than root should be removed or have
their UID changed.
| ||||||
| Rationale | An account has root authority if it has a UID of 0. Multiple accounts with a UID of 0 afford more opportunity for potential intruders to guess a password for a privileged account. Proper configuration of sudo is recommended to afford multiple system administrators access to root privileges in an accountable manner. | ||||||

| Description | To specify password minimum age for new accounts,
edit the file PASS_MIN_DAYS 7A value of 1 day is considered sufficient for many environments. The DoD requirement is 1. The profile requirement is 7. | ||||||
| Rationale | Enforcing a minimum password lifetime helps to prevent repeated password
changes to defeat the password reuse or history enforcement requirement. If
users are allowed to immediately and continually change their password,
then the password could be repeatedly changed in a short period of time to
defeat the organization's policy regarding password reuse.

representations of passwords. In password sufficient pam_unix.so sha512 other arguments... This will help ensure when local users change their passwords, hashes for the new passwords will be generated using the SHA-512 algorithm. This is the default. | ||||
| Rationale | Passwords need to be protected at all times, and encryption is the standard
method for protecting passwords. If passwords are not encrypted, they can
be plainly read (i.e., clear text) and easily compromised. Passwords that
are encrypted with a weak algorithm are no more protected than if they are
kepy in plain text.

| Description | Single-user mode is intended as a system recovery
method, providing a single user root access to the system by
providing a boot option at startup. By default, no authentication
is performed if single-user mode is selected.
| ||||||||||||||||||||
| Rationale | This prevents attackers with physical access from trivially bypassing security on the machine and gaining root access. Such accesses are further prevented by configuring the bootloader password. | ||||||||||||||||||||

outweighs the need to log all actions, and a different setting should be
determined. Details regarding all possible values for ACTION are described in the

| Description | To capture kernel module loading and unloading events, use following lines, setting ARCH to either b32 for 32-bit system, or having two lines for both b32 and b64 in case your system is 64-bit: -a always,exit -F arch=ARCH -S init_module,finit_module,delete_module -F key=modulesThe place to add the lines depends on a way auditd daemon is configured. If it is configured
to use the augenrules program (the default), add the lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl utility,
add the lines to file /etc/audit/audit.rules. |
| Rationale | The addition/removal of kernel modules can be used to alter the behavior of the kernel and potentially introduce malicious code into kernel space. It is important to have an audit trail of modules that have been introduced into the kernel. |

utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file in order to watch for unattempted manual
edits of files involved in storing logon events:
-w /var/log/tallylog -p wa -k logins -w /var/run/faillock -p wa -k logins -w /var/log/lastlog -p wa -k logins |
| Rationale | Manual editing of these files may indicate nefarious activity, such as an attacker attempting to remove evidence of an intrusion. |
| Warnings | warning
This rule checks for multiple syscalls related to login events;
it was written with DISA STIG in mind. Other policies should use a
separate rule for each syscall that needs to be checked. For example:

program to read audit rules during daemon startup (the default), add a line of
the following form to a file with suffix .rules in the directory
/etc/audit/rules.d for each setuid / setgid program on the system,
replacing the SETUID_PROG_PATH part with the full path of that setuid /
setgid program in the list:
-a always,exit -F path=SETUID_PROG_PATH -F perm=x -F auid>=1000 -F auid!=unset -F key=special-config-changesIf the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add a line of the following

system, replacing the SETUID_PROG_PATH part with the full path of that

| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threast.
| ||||||||||||||||||||||||||||
| Warnings | warning
This rule checks for multiple syscalls related to privileged commands;
it was written with DISA STIG in mind. Other policies should use a
separate rule for each syscall that needs to be checked. For example:

They may be caused by an intruder, by incorrect software installation or draft software removal, or by failure to remove all files belonging to a deleted account. The files should be repaired so they will not cause problems when accounts are created in the future, and the cause should be discovered and addressed. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Description | When the so-called 'sticky bit' is set on a directory,
only the owner of a given file may remove that file from the
directory. Without the sticky bit, any user with write access to a
directory may remove any file in the directory. Setting the sticky
bit prevents users from removing each other's files. In cases where
there is no reason for a directory to be world-writable, a better
solution is to remove that permission rather than to set the sticky
bit. However, if a directory is used by a particular application,
consult that application's documentation instead of blindly
changing modes.
$ sudo chmod +t DIR | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Rationale | Failing to set the sticky bit on public directories allows unauthorized
users to delete files in the directory structure.

| Description | By default on Red Hat Enterprise Linux 7 64-bit systems, ExecShield is

ExecShield or is disabled in | ||||||||||||||||||||||||||
| Rationale | ExecShield uses the segmentation feature on all x86 systems to prevent execution in memory higher than a certain address. It writes an address as a limit in the code segment descriptor, to control where code can be executed, on a per-process basis. When the kernel places a process's memory regions such as the stack and heap higher than this address, the hardware prevents execution in that address range. This is enabled by default on the latest Red Hat and Fedora systems if supported by the hardware. | ||||||||||||||||||||||||||

| Rationale | Address space layout randomization (ASLR) makes it more difficult for an attacker to predict the location of attack code they have introduced into a process's address space during an attempt at exploitation. Additionally, ASLR makes it more difficult for an attacker to know the location of existing code in order to re-purpose it using return oriented programming (ROP) techniques. | ||||||||
